Abstract

The invention discloses a tightness-adjustable band saw cutting device which comprises an operation table, a frame and a band saw mechanism. The operation table is arranged on the frame. The band saw mechanism comprises a saw blade, a main roller, an auxiliary roller and a motor. The motor is arranged inside the frame, both the main roller and the auxiliary roller are arranged on the frame, the saw blade is arranged on the main roller and the auxiliary roller, and the output shaft of the motor is connected with the main roller. The band saw mechanism further comprises a tension mechanism which comprises a rail and a screwing handle, the screwing handle is in threaded connection with the rail which is arranged on an axle of the auxiliary roller. The screwing handle on the tension mechanism is regulated to enable spacing between the main roller and the auxiliary roller to be decreased, so that the saw blade is conveniently replaced or mounted. The main roller starts to rotate under driving of a rotating shaft of the motor, the saw blade drives the auxiliary roller to rotate, and the whole device is in an operation state. When a log is manually pushed towards the saw blade and starts to contact with the same, the saw blade is in a tight state under tension. When the saw blade rotates along with the rollers fast and slow, the rail is moved up and down by regulating the screwing handle so as to drive an upper saw wheel to move, and the spacing between the main and auxiliary rollers is enlarged, so that the saw blade is tightened once more.

Description

The band saw cutting device that rate of tension is adjustable

Technical field

The present invention relates to Electromechanical Control field, specifically refer to rate of tension adjustable band saw cutting device.

Background technology

In existing band saw operation, motor drives bands for band to start from top to bottom cutting by saw wheel, and operating personnel push round log to the bands for band of motion from outward, round log is cut, and then with artificial by remaining round log in pushed home, cut for the second time, with this cyclic process.This kind of processing technology is popular long, but also there is more defect: first, under driven by motor, saw wheel rotates, upper wheel utilizes self inertia, under the drive of bands for band, start to rotate, but the tensioning of saw blade and rate of tension is often unstable in process, if cut to the pimple part of timber, easily cause saw blade to fracture, also easily threaten operating personnel's personal safety; While cutting large part timber, also normal generation saw blade is stuck, changes saw blade and extremely bothers, and affects job schedule; The existing monodentate saw blade adopting, can cut during propelling more, pushes back invalid constantly motion, and machinery idle running, wastes a large amount of human and material resources, thereby cause working (machining) efficiency low.

Summary of the invention

The present invention by arrange rate of tension adjustable band saw cutting device, solve timber and add the problems such as saw blade rate of tension shakiness in man-hour, reach the object of cutting safely and efficiently timber.

Object of the present invention reaches by the following technical programs:

The present invention includes operating desk, frame and band saw mechanism, operating desk is arranged in frame, described band saw mechanism comprises saw blade, main roller, secondary roller and motor, and motor is placed in frame, and main roller and secondary roller are arranged in frame, saw blade is arranged on main roller and secondary roller, the output shaft of motor is connected with main roller, also comprises strainer, and described strainer comprises track and screws handle, screw handle and be threaded with track, described track is arranged on the wheel shaft of secondary roller.Regulate the handle that screws on strainer, the spacing of main roller and secondary roller is reduced, be convenient to change or install saw blade; Main roller starts to rotate under the driving of machine shaft, and saw blade drives secondary roller to rotate, and whole device is in running order, and when round log is when manually pushing saw blade and beginning to and contact with saw blade, saw blade is subject to tension force in tight state; When saw blade rotates when sometimes fast and sometimes slow with roller, can screw handle by adjusting, track is moved up and down, thereby drive upper wheel to move, increase the distance between major and minor roller, thereby saw blade is tightened again.

Further, described operating desk is provided with bakie, and saw blade is through bakie, and described bakie below arranges charging box, is provided with discharge door on charging box.A large amount of wood chips and waste residue that during band saw, workbench produces enter charging box by bakie, when waste residue is abundant, open discharge door, get final product collection and treatment waste residue, have avoided dust from flying, have prevented air pollution.

Further, as preferably, described motor is Y4001-4 three phase electric machine.Three phase electric machine can positive and negative rotation, drives the two-way linear motion of saw blade, easier while allowing cutting, particularly runs into saw blade counter regulation saw blade just when stuck, makes it to depart from stuck state.

Further, described saw blade is Double-tooth band saw, and Double-tooth band saw represents that both sides all arrange serrate saw band.The saw blade of bidentate can again cut when timber pushes back, and has avoided the idle running of machine, has saved a large amount of electric power and manpower, has simplified to add work step and play, and has improved the efficiency of processing.

Further, the wheel rim of described secondary roller is provided with fin, is conducive to the tensioning of saw blade and the maintenance of rate of tension, and saw blade work is stablized more.

The present invention compared with prior art, there is following advantage and beneficial effect:

1 the present invention includes operating desk, frame and band saw mechanism, and described erecting is equipped with strainer, and described strainer comprises track, screws handle, and the wheel shaft of secondary roller is placed on track.Only need to regulate the handle that screws on strainer, just can, so that the spacing of main roller and secondary roller reduces, be convenient to Fast Installation and change saw blade.

The two-way linear motion of 2 saw blades of the present invention, easier while allowing cutting, particularly run into saw blade counter regulation saw blade just when stuck, make it to depart from stuck state.

The saw blade of 3 bidentates of the present invention can again cut when timber pushes back, and has avoided the idle running of machine, has simplified work flow, has improved the efficiency of processing.
